Nrbelex writes "The New York Times reports in this week's Science section that hardware and software trojan kill switches in military devices are an increasing concern, and may have already been used. 'A 2007 Israeli Air Force attack on a suspected, partly-constructed Syrian nuclear reactor led to speculation about why the Syrian air defense system did not respond to the Israeli aircraft. Accounts of the event initially indicated that sophisticated jamming technology was used to blind the radars. Last December, however, a report in an American technical publication, IEEE Spectrum, cited a European industry source in raising the possibility that the Israelis might have used a built-in kill switch to shut down the radars. Separately, an American semiconductor industry executive said in an interview that he had direct knowledge of the operation and that the technology for disabling the radars was supplied by Americans to the Israeli electronic intelligence agency, Unit 8200.'"
